This invention relates to bumpers of the charscter used upon automobiles upon the front thereof.

The principal object of the present invention is to produce a bumper of the cushion type of comparatively simple construction and characterized by' strength, durability and resiliency.

With the foregoing and other objects in view, the invention resides in the particular provision, relative disposition, andfuncti'ons of the parts here nafter fully described and illustrated in th'. accompanying drawing, in which:

Figure 1 is a plan view ofthe bum r of the present invention shown as applied to the front chassis extremities, portions of which are shown, of an automobile;

Fig". 2 is a front elevation;

'Fi i, 3 is a transverse sectional View on the line 3-3 of Fig. 1 and looking in the direction indicated by the arrows. f

Referring now more particularly t6" the drawings, it will be apparent that the bumper oi the presentinvention generally consists of a shoclnabsorbing element 10, and supporting an attachinggerir 11, which serves for supporting the element 10 and for effecting the attachment thereof to parts of or. automobile. The element 10-' may be made of any preferred material and may be of any shape "and size. In the present instance the element 10 is made of arhigh grade quality of rubber, or composition rubher and fabric, is of hollow construction to provide an air space. The element 10 is provided with air passages 12, which may be located at any desirable points in the wells of the element 16, and in the present instance are located in the opposite ends thereof. These passages or vents allow the atmospheric air to enter the interior of the element 10, and also permit the air within the element to pass out of the element when the element is subjected to a shock of any kind. It will be noted, in proportion to the volume or head ofair within the element 10, the passages 12 are small, so that the air within the element being subjected to-pressure will be able to yield in that a portion will pass out of the passages 12 but'notso to permit a too ready collapsing of fir.) wall of the element, and, at thelsame time, serving to effectively cushion anyblow or shock applied to the wall of the element;

The supporting and attaching gear 11 includes bars 13 and 14 preferably of metal and each being equal in length to the length of :the element 10. The bar 13 is provided with right-angularl Y disposed portions 15, which respectively (l1 bar 14, as shown in Fig. 1, to prevent relative longitudinal movement of the bars 13 and 14-. The gear 11 also includes holders 16, which are suppcrted by t-ie bars 13 and or new iii: the opposite ends of 14 and serve to yicldably support the ole ment' 10. Each of the holders 16 comprises a. pair of holder members 17, a flexible strap or hand 18, and a fastening element in the form of a bolt 19. Each of the holder members 17 comprises relatively angularly dis osed portions 20 and 21, the portion 20 ailing an opening in the'extremity thereof, and the portion 521 being provided with notches or recesses 22 in spaced relationship. One holder member 1'2 is arranged on to of the bars 13 and 14, the'colges or the g being disposed respectively in the notches 22. The other holder member ll is arranged at the bottom of the hers and its notches 22, respectively receive the lower edges of said bars, as shown most clearly in Fig. 3. The holder niemliers 17 of each holder 16 are arranged in vertical alinement, and openings respectivelyin the portions 21 of the holdermembers accommodate the bolt 19. The strap .or band 18 passes through the openings in the extremities of the portions 20 of the holder members, and passes around the front wall of the element 10, and the ends of the bands are connected by virtue of a biickleare Elli

is attached to parts of an automobile, such as v the extremities 26 of the chassis.

From the foregoing it will be apparent that there has been described a bumper of the cushion'type, by-- virtue of the use of the:

ill!) element 10 of'a vented air-filled character, 1

which is capablevof -withstanding wvere and cushions to therpoi nt of preventing on, necessary breakage either to; the hamper shocks, and which, at the same time, yields attaching gear for support per-ts themselves or to the colliding or collided objects.

What is claimed is:

e v 1. In a bumper, a vented air-filled element of resilient material.

2. In o. bumper, s vented air-filled cylindrical element of resilient material.

3. In a bumper, a vented air-filled element of rubber.

4. In a bumper, a vented air-filled element of resilient material, and a supporting and 'u said element and effecting the attachment tihereof.

5. In a bumper, u vented air-filled element of resilient nmteriul, and a supporting and attaching gear for supporting said element and efiecting the attachment thereof, said geerincluding relatively spaced holders associated with said elenent,each of said holders including a flexibie band embracing a Wall of said element.

6. A bumper comprising a vented air-filled element of resilient material, spaced bars'extending longitudinally with respect to said element, holders carried by said bars, said holders having flexible means for detachably connecting said element to be carried by said. holders, and attaching means carried by one of said bars for effecting the attachment of the bumper.

The combination with the running gees of a, vehicle, ofva vented air element, enfi means for attaching said element to sol": running gear and for yieldingly supportin' said element.
